I am experiencing a very strange problem in my Rails app. I use popen3
to execute an external program. Everything works fine in Mongrel, but
when I use the app with LSAPI, after popen3 all MySQL queries fail with
"Mysql::Error (MySQL server has gone away)". Once I comment out popen3
it works fine again.
The problem is easy to reproduce in any Rails app using LSAPI and MySQL.
Add the following to a controller action:
I found that MySQL connection will be lost even in Mongrel, so it is not a problem LSAPI specific.
As to popen3 not working, what kind of result is expected? seems I did not get any meaningful output under Mongrel as well.
